Buggers! You are right. One didn't come with the car when I first restored it in 2004, nor with a back-up engine I rebuilt a couple years ago.
Thanks, Allen. Had no idea such a thing existed!

The center bolt was loose, the one that goes into the crankshaft to hold the fan extension and pulley hub. Since it also keeps the crank timing gear in place, the gear must have been moving a bit back and forth making that noise. Pulled the timing chain cover and all's well in there, so will be replacing the front oil seal (that was leaking like mad and now I know why) and buttoning up this weekend.
